I'm not sure what was intended. This page intends trees with the ability to speak (who may or may not have faces); if they walk, they walk on roots, not feet of any kind.
Not Ents, dryads, kapres, jidra, mandrake, faduah, or any of those. Trees that can talk. Not to sound rude, just want to make that very clear.
Oh, and before anybody says anything, I call Jidra Physiology and Faduah Physiology. ^_^
